Cheese and potato pie was one of my favourite meals growing up, back then it would have been served as a main with peas and ketchup. I now prefer to serve it as a side with sausages and baked beans, yes, I am still a child at heart!

Bring a 20cm or 8" saucepan of well-salted water to the boil. I use 1 teaspoon of salt in a pan this size.Add in the potatoes whole and unpeeled, and boil until cooked; this should take around 30-35 minutes.
Halfway through cooking the potatoes, peel the onion and drop it into the pan.
Roughly chop the onion.
Drain the potatoes, prick them with a fork and peel off the skin. Then mash the potatoes or pass them through a potato ricer.
Add the butter and onion, then mix to combine.
Add the cheese, beaten egg, milk, and mustard to the mash, then mix well; you should have quite a "wet" mash.
Have a taste here and add more salt if required, although it should not be!
Place the mash into a greased or buttered casserole dish (around 0.5 litres in size) and top with the remaining cheese.
Slice the tomato into 3-4mm (⅛-¼) thick slices and add them to the top of the mash.
Bake in an oven at 200°C or 400°F for 15-20 minutes.
